KryptoniteNew York Fahgettaboutit Mini Bike U-Lock, Heavy Duty Anti-Theft Bicycle U Lock, 18mm Shackle with Keys, Ultimate Security Lock for Bicycles E-Bikes Scooters,Black

This is highly rated on consumer reports. The lock is heavy and solid. It is a quality bicycle lock.

Superb built quality, going on nearly 2 years of use and it's not flinched once. Couple things to note; The plastic sleeve that covers the keyhole is rather flimsy and will likely come off with rough use. This does not affect the function much, if anything it makes accessing the lock easier. Otherwise, be mindful of the spacing your bike has! This is a VERY thick U-Lock and will have much less margin of error than something like a chain or wire-lock.All disclaimers aside, it is one the the sturdiest and safest locks I've used so far. Absolutely worth every penny.

If you don’t want your bike stolen, get this lock!When I got this lock, it not only looked like a beast and felt like one, but it also had some serious weight to it. Totally worth every penny—super high quality! With the Fahgettaboudit lock, I feel confident no one can steal my bike. I bought it for my (Lectric) e-bike, and it works like a charm.I also love that it comes with multiple keys and that you can register them in case they’re ever lost or stolen. A quick note: if I’m going off-roading or don’t plan to use the lock, I take it off the bike because of the added weight.Overall, 10/10—love it and highly recommend it!

This is a small shackle as described, but enough to lock up my E-bike securely if I can park close to a rack. Very heavy duty.

This lock is extremely bulky and heavy but overall there is no way anyone is breaking it or taking my scooter. I use this lock to lock my scooter on a college campus as I had someone steal my previous scooter with a different lock and wanted to be extremely cautious with a new scooter. Overall, there is absolutely no way someone is getting around this lock. The downside is that when I put it in my backpack, it weighs it down greatly. The lock is not very large but weighs around 10 pounds and can be an annoyance to carry around and is not easy to mount to your scooter while riding since it is so heavy. The lock is easy to lock and unlock and there are many safety measures that would prevent thieves from stealing it, plus it comes with a warranty if your bike or scooter is stolen! Overall great investment for your equipment.

This lock is a huge step up from my old random chain lock I had. The lock has 3 keys total making it very nice in case you lose any and the product feels super secure. I trust this lock to protect my electric scooter for when I take it to school. The lock has some weight to it but nothing that would be considered crazy. I’ve been using it for around 2 months and have zero complaints. The price was a little steep but after using this lock it feels entirely justified and worth spending the money to protect my electric scooter.

You get what you paid for and I am happy to a strong secure lock for my bike.

I use this to lock up my e-bike around the city and it works well.
